Obi was formerly a mercenary and assassin before handing himself over to Zen calling him "Master”, being hired as Zen's attendant before being officially raised to being Zen's personal messenger. he has heightened senses, advanced combat skills, and keen eye to detect change, though prefers to keep his face hidden to feel more at ease. He has cat-like amber eyes and he loves pranking others. cheerful and outgoing can be deadly serious if needed.
